a multi entry visa allows you to leave and return to Thailand as many times as you want which extends a one year visa to 15 months. You don't have to go to Ranong every 3 months you can stay in Thailand for one full year if you want without leaving. You just have to report to immigration every 90 days to do a report which takes 5 minutes.
there's nothing stopping him from visiting that Burmese Island every 3 months if he wants to. He will get stamped back in with his multiple entry visa. He must really like that Island.
if the expiry is one year after it was issued that's when you have to leave. But in the meantime you will have to do 90 day reports at your local immigration office.
if you have a multiple entry as an addition to your non O you can of course go in and out as much as you want. But you don't have to. I have a non O and I haven't been out of the country since 2015.
I report to Thai immigration every 90 days via a website on my phone in the comfort of my home. Lol. It takes 2 minutes. Such hardship. I don't need to have bars on my windows in Thailand like you do in the Philippines.
that's very surprising to hear. I've been using Lazada for years without any problems. On a couple of occasions that I've had to return something that's faulty, no questions asked, refunded in a few days. Lazada as a policy will take the side of the customer and not the third party vendor if there is a dispute. The last time I returned quite a pricey item Lazada said as you have been a long-term customer we're not even going to bother to examine the goods first, we will refund you immediately. I can't fault them.
